Abstract

The invention discloses a light-emitting diode (LED) device. The LED device comprises a plurality of LEDs, a state detecting unit, a power supply control unit and a processor unit, wherein when more than one LEDs are out of order, the other LEDs can operate normally; the state detecting unit is coupled with the LEDs; the power supply control unit provides a power source and outputs the power source to the LEDs; and the processor unit instructs the power supply control unit to adjust the power source and output the power source to the LEDs according to the state signal provided by the state detecting unit. By using the light-emitting diode device with the compensating mechanism, the power can be rated.

Description

technical field [0001] The invention relates to a light emitting diode device, in particular to a light emitting diode device with a compensation mechanism. Background technique [0002] Light Emitting Diode (LED for short) was born in the 1960s, from red LED, green LED, all the way to blue LED, until 1998 did not really see the commercialization of LED. LEDs have functions such as power saving and fast switching speed. At present, LEDs are widely used in indication functions, and this field is also the first market for LEDs to enter, such as outdoor display boards, traffic lights, and flat lighting. As high-end mobile phones use LEDs as backlight sources, LEDs have opened up new application areas. [0003] The application range of LED is quite wide, from early mobile phones, small devices such as remote controls, etc., to the emergence of high-brightness LEDs in recent years, and the application range has expanded to products such as automobiles, lighting, and large outdoo...
